HP-UX WLM A.03.02 runs under the following HP-UX operating systems and hardware:

Operating SystemsHardware
HP-UX 11i v1 (B.11.11)HP 9000 servers
HP-UX 11i v2 (B.11.23)HP 9000 servers and HP Integrity servers
HP-UX 11i v1 (B.11.11) and
HP-UX 11i v2 (B.11.23)
Servers combining HP 9000 partitions and HP Integrity partitions; in such environments, HP-UX 11i v1 (B.11.11) supports HP 9000 partitions only

HP-UX WLM A.03.02.02 runs under the following HP-UX operating systems and hardware:

Operating SystemsHardware
HP-UX 11i v3 (B.11.31)HP 9000 servers, HP Integrity servers, and servers combining HP 9000 partitions and HP Integrity partitions

HP-UX WLM provides goal-based workload management. This management enables automatic resource allocation and application performance management through the use of prioritized service-level objectives (SLOs). It provides this functionality by automating features of HP Process Resource Manager (PRM), HP-UX Virtual Partitions, nPartitions, and processor sets.

HP-UX WLM offers the following features:

  • Automatic allocation of CPU resources (cores) to your most critical applications
    (allocation of time slices on cores as well as whole cores when managing processor sets, virtual partitions, or nPartitions)

    A core is the actual data-processing engine within a processor, where a single processor might have multiple cores, and a core might support multiple execution threads; for more information, see the WLM HP-UX Workload Manager User’s Guide.

  • User-configured allocation of real memory and disk bandwidth resources

  • Shares-based and goal-based SLOs

  • CPU shares-per-metric allocations, which allow you to give a workload, for example, 2% of the CPU resources for each process in the workload

  • Multiple SLOs at different priorities, allowing you to have a “must meet” goal and optional stretch goals for each workload

  • Passive mode for analyzing a configuration’s behavior

  • Audit and billing data

  • Ability to set minimum and maximum amounts of cores available to a workload

  • Time-based and metric-based activation of SLOs, including the ability to activate SLOs associated with a Serviceguard package on failover

  • GUI for creating, modifying, and deploying WLM configurations locally and on remote systems

  • Integration with HP Systems Insight Manager, allowing you to remotely control WLM running on numerous nodes from a single point of administration
